"We need to announce the team make-up at least six-to-eight weeks prior to the Motocross of Nations and that means we should have it all worked out by early August.
"We need to have time to prepare as a team and I'll be monitoring the Kiwis who are currently racing in Australia and back home, to ensure we have the best team possible. Riders who feel they are in the mix should concentrate on staying healthy and performing well.
"Obviously Mount Maunganui's Cody Cooper will be one rider we'll look at closely to be in the team again, but other riders will be catching the eye of the selectors, too."
Coppins said it was a huge honour for a rider to be selected to race for his country at the Motocross of Nations and New Zealand had a proud history in the event. Team New Zealand has been on the podium on three occasions: at Foxhills, in England, in 1998; at Namur, in Belgium, in 2001, and at Matterley Basin, in England, in 2006.
In all three instances, Coppins was one of the New Zealand riders.
Cooper, Coppins and Taupo's Townley were the New Zealand team which finished fourth in France in 2005 and third in England in 2006.
Coppins and Cooper were again teammates - this time with BikesportNZ.com rider Kayne Lamont, of Mangakino, as the team's third rider - when Team New Zealand finished 15th overall in the deep sand of Lommel, in Belgium, last season.
Cooper has his fingers crossed that he is selected for the squad again this time around. "I hope I do get picked for the Motocross of Nations squad. I have raced at this German track before, although it was a Grand Prix event when I was about 17, so that's a long time ago, but I think we'll do well there."
